By default, Hum distributes the audience with the multi-armed bandit algorithm, but you can change this to distribute by segments for the Stage 1 of your campaign. If you distribute by segments, you set a target segment per touchpoint.
Multi armed bandit distribution will optimize to display higher performing touchpoints over time.
Segments audience distribution sets different segments to target each touchpoint in a given stage.
Important Note: Audience Distribution for Segments is not guaranteed. If there is overlap in the segments selected (Profile is a part of 2 or more selected segments), Hum will use multi-armed bandit to decided which touchpoint to show.
What is a Multi-Armed Bandit Algorithm?
Unlike traditional A/B testing, MAB uses machine learning algorithms to dynamically shift traffic towards better-performing campaign, touchpoint or variants. Where A/B testing is about determining a winner, MAB is about getting you as many conversions as possible for your campaign. Learn more here.
How to change your audience distribution method for a campaign
- In a Live Engagement Campaign, click the more menu (three vertical dots) in the Audience portion of the campaign builder page.
- Click Edit
- Hum defaults to Multi Armed Bandit. Select Segments if you wish to change it.
- If you’ve selected Segments you will be prompted to “select a segment for each touchpoint” from a drop down list of existing segments or you can build a new segment.
- Click Save Changes.
- To make changes to any of those selections, repeat steps 1-5.
